The evening of Wednesday 8th October 2014 promised a Lunar Eclipse, accordingly the monthly meeting of “Sydney City Sky Watchers” was delayed by two days and plans were made for a combined meeting and observing session. The meeting was at the usual venue: Sydney Observatory.
The equipment I prepared was my compact Celestron 4GT telescope, Canon 5Dmkii camera and a whopping 56cm (22″) video monitor. This is the second public astronomy event where I have used this setup, the plan is to show on screen the event of interest, many people can watch the same event and being able to point at the monitor is very helpful in talking about the event.
If that was the plan, then the reality was that once again we were competing with clouds to get the odd peek of the eclipse, this time the cloud was on multiple levels, all travelling in different directions. Still the viewing was a modest success, many people did get to see various stages of the eclipse. Having a live feed from Los Angeles (Griffith Observatory) was also helpful. Here are some photos from the event, also some more pics taken after the event from home of the partial end stages of the eclipse, please realise that photographing the moon presents an impossible range of contrast, some of the moon is in full sunlight, other parts are in diffuse shadow.
This photo represents the best views we had of the early stages of the eclipse:
Occasionally the clouds parted and we saw this:
While these are a series of photos of the latter stages of the eclipse, taken at various exposures:
Fixing POPFILE email classifier
I have long used an email classifier called popfile to assist me with managing email spam.
Recently it stopped working. It turns out that it has a conflict with the popular and fantastically useful remote desktop viewing and support program called ANYDESK. The default configuration of both anydesk and popfile use port 7070. This article is about resolving this conflict by changing the popfile configuration.
My Linux system uses Ubuntu-Mate 18.04 LTS, this solution has also been applied to 20.04 LTS.
In investigating why popfile was not working, I went to the logs located at /var/log/popfile I found in the newest logfile:
html: 76: Couldn’t start the html interface because POPFile could not bind to the listen port 7070
So the problem is with port 7070, looking at what it is being used for:
sudo lsof -i :7070
Which told me that ANYDESK is using that port and it also gave me the PID of that process. So I used this PID to stop anydesk for this session:
sudo kill “prosess ID from above”
Then test that there is no program on this port any more:
sudo lsof -i :7070
(no result, hence port not in use)
I could then start popfile and change its configuration:
cd /etc/init.d/
sudo sh popfile start
Result is: Starting popfile: popfile.
Checking with: sudo lsof -i :7070
Shows that popfile is connected.
Then in my web browser I opened popfile at the old conflicted port:
http://127.0.0.1:7070/
and for the fist time in a while I can access the popfile controls.
Then selected the “Configuration” tab, in section “User interface web port:” changed the number from 7070 to 7080 and click apply.
Then to change the configuration:
cd /etc/popfile
sudo ed defaults
change the UIPORT from 7070 to 7080 and write the changes
Then either stop and start popfile to pickup the new confifguration, OR just reboot the computer.
cd /etc/init.d
sudo sh popfile stop
sudo sh popfile start
This has restored popfile’s functionality.
Now the web browser opens popfile at the new port:
http://127.0.0.1:7080/
